Patent DE-4135119-A1 (DE)
Inventor: WOSNITZA FRANZ PROF DR ING
IPC: C04B40/02
Filed: 1991-10-24
Abstract: The invention relates to a method for autoclaving porous, lumpy materials by means of pressurised steam, the autoclaving process comprising, successively, a steam-operated heating phase, a holding phase and an expansion phase for pressure and temperature, the holding phase comprising a drying process in which the autoclave, going beyond compensating for heat losses and being set to a temperature above the evaporation temperature of the water, is heated indirectly and the material is dried by a controlled blowing-off of steam-containing heating medium from the interior of the autoclave. In order to obtain as dry a product as possible using as little energy as possible, it is provided that the drying process essentially extends over the entire holding phase, one or more autoclaves in the holding phase being supplied with sufficient heat for the steam necessary for a heating phase to be blown off and, after previous intermediate storage if appropriate, used to operate a heating phase. <IMAGE>

Patent DE-4234737-A1 (DE)
Inventor: WIBMER ALBERT
IPC: A01G9/10
Filed: 1992-10-15
Abstract: The invention concerns a planting-out pot made of environmentally acceptable materials which will rot or are non-toxic. An example of a prior art pot of this kind is German utility model No. 82 12 729 comprising a bitumen-paper stamping held in the shape of a pot by wire staples. The disadvantages of this design include the large amount of waste sheet produced by its manufacture and the fact that it is not easy for the plant roots to pass through the pot walls and bottom. The aims of the invention include avoiding the production of waste, and even the use of waste in the manufacture of the pots, as well as making it easier for the plant roots to pass through the pot walls and bottom. The invention achieves these aims by calling for the pot bottom to continuously overlap the pot walls, which consist of a separate piece with an end overlap zone of the same kind, the overlap zones being bonded with adhesive. The pot is made of fibrous material. The advantages of the invention are the small amount of waste left from the sheet from which the pot bottom and wall blanks are stamped, as well as the greater ease with which roots can pass through the fibrous material.
